Why is concave mirror used in Searchlight & head lights? When the bulb of headlight is placed at focus of concave mirror, it allows the light to spread out to infinity (longer distances) and at infinity they are approximately parallel. Hence, concave mirrors are used in the headlights of vehicles. What is the role of […]
What are some long term consequences of desertification?
What are some long term consequences of desertification? Desertification reduces the ability of land to support life, affecting wild species, domestic animals, agricultural crops and people. The reduction in plant cover that accompanies desertification leads to accelerated soil erosion by wind and water. How can we reduce land degradation? 5 possible solutions to soil degradation […]
Why CSMA CA is used for wired network?
Why CSMA CA is used for wired network? CSMA/CA tries to reduce the frequency of these collisions and provide a plan at the same time on how to proceed if a collision does occur. The protocol is also important because the transmissions in the wireless networks cannot run in the same order (due to the […]

What are the major steps in homeostasis?
What are the major steps in homeostasis? Adjustment of physiological systems within the body is called homeostatic regulation, which involves three parts or mechanisms: (1) the receptor, (2) the control center, and (3) the effector. The receptor receives information that something in the environment is changing. What happens to the body after exercise homeostasis? To […]
What two special image are formed by concave mirror?
What two special image are formed by concave mirror? Concave mirrors can produce both real and virtual images; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real); they can also be enlarged, reduced, or the same size as […]
Are Discouraged workers part of the labor force?
Are Discouraged workers part of the labor force? Since discouraged workers are not actively searching for a job, they are considered nonparticipants in the labor market—that is, they are neither counted as unemployed nor included in the labor force. We define potential labor market participants as the number of discouraged workers who reenter the labor […]
What is the best color to reflect heat?
What is the best color to reflect heat? TL;DR (Too Long; Didn’t Read) The only color that does not attract heat is white because white objects reflect all visible wavelengths of light. Black – the color that absorbs all visible wavelengths of light – attracts the most heat, followed by violet, indigo, blue, green, yellow, […]
How does deicing with salt negatively impact the environment?
How does deicing with salt negatively impact the environment? How does de-icing roads with salt negatively impact the environment? It removes necessary salt from the local water courses. c. The high salinity of the surface runoff is harmful to freshwater ecosystems. What are the environmental impacts of salt? But it can also have serious, negative […]
